I forgot to ask, what is the relevance of 15x chips?
I did a detailed explanation of this somewhere but I can't find it, I should have made a note of where it was, bugger.

A better way of describing the "15x rule" for calling raises with small to medium pocket pairs is that if you can win less than 10 times the chips you need to call, you should generally fold, but if you can win more than 20 times the chips you need to call, you should generally call. In between it's a judgement call but generally speaking I tend to call provided I can win at least ~15 times the chips I need to call.

Where this comes from is that you hit a set on the flop with a pocket pair about 11.8% of the time or 1 time in 7.5. Assuming the opp whose raise you are calling stacks off every single time you hit a set on the flop then you would break even if you could win 7.5 times the chips you need to call. However, opps won't stack off every time so you need a bit more. Against a terrible and/or aggressive player, you can call a bigger raise because they will stack off with crap like middle pair, against a better and/or more passive player you can't call such a big raise because they won't stack off as often.

Hope that makes sense.
